In the accompanying diagram ab is tangent to circle O at B and ACD is a secant.
If AB=9 and AD=27, find AC
Answers
Answer:
AC = 3
Step-by-step explanation:
Based on tangent and secant theorem, thus:
AB² = AC × (AC + CD)
AB = 9
AD = AC + CD = 27
Plug in the values
9² = AC × (27)
81 = AC × 27
Divide both sides by 27
81/27 = AC
3 = AC
AC = 3

Which function rule defines f(x)?
Answers
Answer:
B. f(x) = -2x - 5
Step-by-step explanation:
✔️Find the rate of change:
Rate of change using two of the given pair, say (0, -5) and (1, -7)
Rate of change (m) = ∆f(x) / ∆x = (-7 -(-5)) / (1 - 0) = -2/1 = -2
✔️Find y-intercept (b):
y-intercept (b) = -5 because the y-intercept is the value of f(x) when x = 0.
✔️Substitute m = -2 and b = -5 into f(x) = mx + b
Thus,
f(x) = -2x + (-5)
f(x) = -2x - 5
